ABSTRACT:
The present invention provides a process for producing a styrene or styrene derivative polymer of narrow molecular weight distribution, which comprises (co)polymerizing a styrene or styrene derivative monomer using, as the catalyst system, a mixture of a free radical compound, a radical polymerization initiator and a phosphorus compound. With the present process, the polymerization speed is very high and a monodisperse polymer of narrow molecular weight distribution can be obtained easily.
